ANTENNA (GPS)

There is a lithium battery (CR 2032) in a holder on the
main circuit board of the GPS antenna. If replacement
is necessary, notify an authorized Raymarine® dealer of
factory repair center.
These batteries are specified to last 3 to 5 years. Even
with a low battery, the unit will get a fix; it may just be a
bit slower to lock on if power is cycled on the unit.
